According to a news release from the California Department of Toxic Substances Control, the facility receives hazardous waste, repackages it into larger containers then ships it to other facilities for disposal.

The DTSC said there have been at least two fires and an explosion at the facility in the past two years.

A fire in August 2011 led to two firefighters being slightly injured.

Last month, chemicals mixed together in a bin led to a fire that smoldered for five hours before being noticed by a passerby, according to DTSC.

"In spite of past assurances from the facility that it has the practices and procedures in place to prevent these kinds of incidents, the third event has led DTSC to compel the facility to cease operations until such time they can demonstrate it can be operated in a safe manner," said Brian Johnson, deputy director of the hazardous waste program in a released statement.

The agency said that fires and explosions at the facility "could potentially release hazardous waste to the environment."

A call to the company requesting comment was not immediately returned.

It was not immediately known how many jobs would be affected by the shutdown.

In 2010, DTSC fined the company $600,000 for previous violations.

The agency said it may pursue additional penalties for the recent incidents.
